Hi There!
I always try solving my problems without posting to the forum, but today my site drives me SO insane that I see no other way :s I really hope some genius here can help me...
When I try to add a page to my (custom) menu, the loader-image appears and then nothing happens. It just keeps on loading forever (well, I didn;t try forever yet, but for a long long time at least!). No page refreshes or anything else.
I de-activated all the plugins: no change. I changed me custom theme to twenty twelve, and hey! It worked again! So it has something to do with the theme...
But how does a theme influence this function in wordpress?
I did update to version 3.5.1 not so long ago, so maybe it has something to do with that maybe? (from 4.9 I believe...)
Thanks for your help...
S
